Answer 1

1.Given

Medication :Keflex

Route:Oral

Order:250mg

Available :250mg/capsule

Weight:50 pounds

1pound=0.454kg

Then 50pounds=??

=22.7 kg (50×0.454÷1)

Ans:a.The weight of the child is 22.7kg

Recommended dose :25_50mg/kg/day

If 25mg/kg/day (1kg=25mg/day)

then 22.7kg=??

Cross multiply and divide

= 567.5 mg/day(22.7×25÷1)

If 50 kg

= 1135mg/day(22.7×50÷1)

Ans:b.The recommended dose range is 567.5mg to 1135mg/day

c.The order is safe because the child is ordered 4 doses

If 1 dose =250mg

Then 4 dose=1000mg (250×4)

1000mg falls under the recommended dose range and hence safe

d. Given 1 capsule =250mg

Then 1000mg=??

=4 (1000÷250)

Ans:4 capsules to be administered

Available :0.05mg/ml

Recommended dose:0.035_0.06mg/kg/day

For 0.035mg/kg/day

3×0.035=0.105mg/day

For 0.06mg/kg/day

3×0.06=0.18mg/day

Ans:The safe recommended dose range is 0.105mg to 0.18mg/day

c.The dose of 12.5mg is not safe and is more than the recommended dose

d. No ,the order is not safe

3.To calculate the weight multiply 50lb by 0.454kg

=22.7kg

Ans:A.22.7kg

Order:25mgIV

Frequency :6 hourly

The recommended dose is 5mg/kg/day

Then22.7 kg=??

=113.5 mg/day (22.7×5÷1) for a child weighing above 12 kg

b.The recommended safe dose is 113mg/day

c.The order is safe because if 1 dose =25mg then 4 dose =100mg which is within the normal range

d.Available : Benadryl 12.5mg/ml

=2ml (25÷12.5 )

Ans:2ml

4.Given

Weight :28lb(12.7kg or 13kg)

For children between 11 to 30 kg the fluid requirement is 1000ml +50ml for every kg above 10kg

So for 13 kg=1000ml+50+50+50

=1150ml

Ans:a.1150ml

b.To calculate the flow rate

Volume:1150ml

Time=without

Drop factor:60gtt (standard rate for children)

Flow rate=Total volume ×drop factor ÷Time×60

=1150×60÷24×60

=47.9 or 48 gtt

b.48 ml/hour
